Basics & Structures of the Lymphatic System

The video provides an in-depth overview of the lymphatic system, highlighting its often overlooked importance in anatomy and physiology. It explains the role of lymph, lymphatic vessels, and nodes in fluid transport and immune response. The video also covers secondary lymphatic organs like the spleen and thymus, and details the function of the Cisterna Chyli and thoracic duct in lymph drainage.

What is the primary function of lymphatic vessels?

• To transport blood

• To carry lymph

• To store nutrients

• To produce hormones

What percentage of fluid is typically reabsorbed at the venous end of the capillary bed?

• 50%

• 75%

• 100%

• 85%

What role do lymph nodes play in the lymphatic system?

• They store fat

• They filter lymph and mount immune responses

• They produce red blood cells

• They regulate body temperature

How are lymph nodes similar to TSA agents?

• They store lymph

• They produce lymph

• They transport lymph

• They scan for pathogens in lymph

What is the primary function of the spleen in the lymphatic system?

• To degrade old red blood cells and monitor blood for pathogens

• To store lymph

• To produce hormones

• To produce lymph

Where do T cells mature in children?

• In the bone marrow

• In the spleen

• In the thymus

• In the lymph nodes

What is the function of the Cisterna Chyli?

• To act as a checkpoint and collect lymph from lower body

• To produce lymph

• To produce red blood cells

• To store blood

Which duct drains the majority of the body's lymph?

• Subclavian duct

• Cisterna Chyli

• Thoracic duct

• Right lymphatic duct

Which regions are drained by the right lymphatic duct?

• Left arm and both legs

• Right arm and right side of the head and neck

• Entire abdominal region

• Left side of the torso

Where does the thoracic duct return lymph to?

• Right subclavian vein

• Left subclavian and internal jugular veins

• Right internal jugular vein

• Cisterna Chyli
